(46) is higher than present study (29.98). So it can be said more liquid limit, more salinity effect on soil behavioral parameters. In Figure 5 optimum moisture with saline water versus optimum moisture with fresh water is drawn for five studies. As seen, most of the samples have located under diagonal line that shows optimum moisture decreases as water salinity increases. In the present study and Alamdar, 1999 changes percentage in optimum moisture is lower than other studies. The reason may be the lower liquid limit of the soils in these two studies.
